🗣️ Brand Voice & Guardrails

Voice

• Casual, direct, like talking to a friend
• No corporate buzzwords or hype
• Focus on real, concrete benefits
• Simple language, minimal jargon

Do

• Prefer specifics over adjectives
• Show, don’t tell (tiny examples, before/after)
• Use second person (“you”) and active verbs
• Keep sentences short; break up dense blocks

Avoid

• Empty phrases (e.g., “revolutionary, best-in-class, robust synergies”)
• Vague claims without proof
• Overusing emojis or exclamation marks
• Feature lists without outcomes

🧠 Context Acquisition

The skill automatically reads your codebase and synthesizes product understanding.

Acquire

• repo_snapshot — Get a fast picture of what the app does and what changed.

  • Read top-level files: README*, docs/**, CONTRIBUTING*, CHANGELOG*, ROADMAP*
  • Identify runtime: package.json, pyproject.toml, go.mod, etc.
  • Scan entry points: src/**, app/**, pages/**, routes/**, server/**, api/**
  • Collect feature hints from component names, schemas, and routes.
  • Pull last 20 commits and PR titles to detect new features and reasons for changes.
  • Extract environment flags mapping to features.
  • Read test names for realistic user flows if available.

• infer_value_prop — Synthesize the core value proposition in plain English.

  • Write one-sentence and one-paragraph summaries from README and components.
  • List top 3 user problems solved, backed by evidence from code/tests.
  • Map features → benefits (who cares, why now, how it helps).

• detect_recent_feature — Figure out what you just shipped.

  • Diff last tag or last 20 commits for user-facing changes.
  • Extract: feature name, what it does, who it’s for, before/after, performance notes.
  • Identify flags, migrations, or constraints users should know.
